Having heard from a reliable source, apparently AKRA is going to change the rule on exhaust pipes in mid year. The reason this was noted was because of trying to buy pipes for this year and the suppliers not having the quanity needed, they are letting their supplies dwindle so the new pipe can be brought in and they wont get caught sitting on a defunct pipe. The new pipe will be the RLV 5438 as i have been told. Be aware of this and it might be something we have to deal with to be in sync with other tracks that may want to race with us.
